IMPROVEMENT IN THE MODES 0F ATTACHING JOURNALS T0 FEED-ROLLERS.

Specification forming part of Letters Patent No. 142,364, dated September 2, 1873; application filed August 9, 1873.

. To all whom it may concern:

Be it known that I, Gnonen M. AMSDEN, of South Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Attaching Journals to Feed-Rollers, of which the following is a specification My invention consists in attaching the shafts or journals of hollow feed and other rollers to them by casting the rollers around and upon portions of the journals which are .larger at the inner end than at the ends of the rollers, and fitting nuts on the journals to screw against the rollers and draw the journals tight in the holes of the rollers, in case they become loose by the shrinkage of the metal in cooling or from any other cause.

Figure 1 is a longitudinal sectional elevation of a feed-roller and a journal connected according to my invention, the section being taken on the line m as of Fig. 2. Fig. 2 is a transverse section taken on the line y y of Fig. 1.

Similar letters of reference indicate correspondin g parts.

A is the hollow feed-roller, such as used in planing-machines, also in spinning, carding,

and othermachines, both for feeding and drawing. B is the journal, which I connect to the roller by first making that portion, 0, which is to enter the end of the roller to gradually increase in size inward from the point where the end of the roller is to come, so that it cannot draw out when once fitted in, and fitting it with a thread, D, to receive a nut, E. This journal I fit in the mold so as to project into the space to be filled by the molten metal and be surrounded by it; then, after casting the roller and allowing it to cool, I screw on the nut E and draw the journal firmly into the socket in case it is loose, and to prevent it from coming loose.v

To secure the journal against turning, a groove, F, may be formed in it to be filled by the cast metal; or a spline may be fitted in the journal to be surrounded by the molten metal.

This plan is very much simpler than the va-v rious plans that have beencontrived heretofore for this purpose, and, it is believed, is morevefficient than any.

Having thus described my invention, I claim as new and desire to secure by-Letters Patent- The securin g the journals in the roller 13 by casting the latter on the conical portions O of the journals, and combining the tighteningnuts with said journals and rollers, either with or without a groove or spline in the journals, substantially as specified.
